- * such as Defect Pixel Correction, Color Space Conversion etc to
- * pre-process the Raw Bayer RGB data, before writing it to SDRAM.
- * This file is named DM644x so that other variants such DM6443
- * may be supported using the same module.
- *
- * TODO: Test Raw bayer parameter settings and bayer capture
- * Split module parameter structure to module specific ioctl structs
- * investigate if enum used for user space type definition
- * to be replaced by #defines or integer

- * Driver name : VPFE Capture driver
- * VPFE Capture driver allows applications to capture and stream video
- * frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
- * TVP5146 or Raw Bayer RGB image data from an image sensor
- * such as Microns' MT9T001, MT9T031 etc.
- *
- * These SoCs have, in common, a Video Processing Subsystem (VPSS) that
- * consists of a Video Processing Front End (VPFE) for capturing
- * video/raw image data and Video Processing Back End (VPBE) for displaying
- * YUV data through an in-built analog encoder or Digital LCD port. This
- * driver is for capture through VPFE. A typical EVM using these SoCs have
- * following high level configuration.
- *
- * decoder(TVP5146/ YUV/
- * MT9T001) --> Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
- * data input | |
- * V |
- * SDRAM |
- * V
- * Image Processor
- * |
- * V
- * SDRAM
- * The data flow happens from a decoder connected to the VPFE over a
- * YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
- * and to the input of VPFE through an optional MUX (if more inputs are
- * to be interfaced on the EVM). The input data is first passed through
- * CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
- * does very little or no processing on YUV data and does pre-process Raw
- * Bayer RGB data through modules such as Defect Pixel Correction (DFC)
- * Color Space Conversion (CSC), data gain/offset etc. After this, data
- * can be written to SDRAM or can be connected to the image processing
- * block such as IPIPE (on DM355 only).
- *
- * Features supported
- * - MMAP IO
- * - Capture using TVP5146 over BT.656
- * - support for interfacing decoders using sub device model
- * - Work with DM355 or DM6446 CCDC to do Raw Bayer RGB/YUV
- * data capture to SDRAM.
- * TODO list
- * - Support multiple REQBUF after open
- * - Support for de-allocating buffers through REQBUF
- * - Support for Raw Bayer RGB capture
- * - Support for chaining Image Processor
- * - Support for static allocation of buffers
- * - Support for USERPTR IO
- * - Support for STREAMON before QBUF
- * - Support for control ioctls

+ * Driver name : VPFE Capture driver
+ * VPFE Capture driver allows applications to capture and stream video
+ * frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
+ * TVP5146 or Raw Bayer RGB image data from an image sensor
+ * such as Microns' MT9T001, MT9T031 etc.
+ *
+ * These SoCs have, in common, a Video Processing Subsystem (VPSS) that
+ * consists of a Video Processing Front End (VPFE) for capturing
+ * video/raw image data and Video Processing Back End (VPBE) for displaying
+ * YUV data through an in-built analog encoder or Digital LCD port. This
+ * driver is for capture through VPFE. A typical EVM using these SoCs have
+ * following high level configuration.
+ *
+ * decoder(TVP5146/ YUV/
+ * MT9T001) --> Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
+ * data input | |
+ * V |
+ * SDRAM |
+ * V
+ * Image Processor
+ * |
+ * V
+ * SDRAM
+ * The data flow happens from a decoder connected to the VPFE over a
+ * YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
+ * and to the input of VPFE through an optional MUX (if more inputs are
+ * to be interfaced on the EVM). The input data is first passed through
+ * CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
+ * does very little or no processing on YUV data and does pre-process Raw
+ * Bayer RGB data through modules such as Defect Pixel Correction (DFC)
+ * Color Space Conversion (CSC), data gain/offset etc. After this, data
+ * can be written to SDRAM or can be connected to the image processing
+ * block such as IPIPE (on DM355 only).
+ *
+ * Features supported
+ * - MMAP IO
+ * - Capture using TVP5146 over BT.656
+ * - support for interfacing decoders using sub device model
+ * - Work with DM355 or DM6446 CCDC to do Raw Bayer RGB/YUV
+ * data capture to SDRAM.
+ * TODO list
+ * - Support multiple REQBUF after open
+ * - Support for de-allocating buffers through REQBUF
+ * - Support for Raw Bayer RGB capture
+ * - Support for chaining Image Processor
+ * - Support for static allocation of buffers
+ * - Support for USERPTR IO
+ * - Support for STREAMON before QBUF
+ * - Support for control ioctls
